Are the GTM turbo manifolds the same regardless of what turbo size you go with? For example, is the manifold the same whether you go with the small GT28 or a GT30? Also, are the turbos they use off-the-shelf Garretts? It looked like it, but I'd rather be sure.
First one to derail this into a "GTM sucks fat dong" thread gets a mushroom stamp on their forehead.
